1 Claim.

This invention relates to a drawing or ruling pen.

The invention comprehends a drawing or ruling pen of the reservoir type having a discharge opening for feeding ink to ink-applying blades together with means for freeing the discharge opening of encrusted or dried ink.

Another object of the invention is to provide a feed tube which is connected with the body of the pen for movement axially thereof and through which protrudes a fixed central stem for insuring a ready flow of the ink through the discharge opening in the feed tube and for freeing the said opening from encrusted or dried ink by the axial movement of the feed tube.

Still another object of the invention is to provide a reservoir type pen with ink-applying blades which are swngably and detachably associated with the forward end of the pen for facilitating cleaning thereof.

Still another object of the invention is to provide a drawing or ruling pen of said character which embodies an improved construction and arrangement of parts by which the ink is forcibly fed to the applying blades and by which the parts may be readily freed of encrusted ink.

With the foregoing and other objects in View, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

In the drawings:

Fig. 1 is an enlarged vertical sectional View through a drawing or ruling pen of the reservoir type constructed in accordance with the invention.

Fig. 2 is a view in elevation thereof showing the ink-applying blades swung into angular relation therewith.

Fig. 3 is a cross-sectional View taken approximately on line 3-3 of Fig. 1.

Fig. 4 is a similar View taken approximately on line 4-4 of Fig. 1.

Fig. 5 is a fragmentary sectional view showing the filler sack in twisted formation.

Fig. 6 is a cross-sectional view taken approximately on line 6--6 of Fig. 1.

Referring to the drawings by characters of reference, the pen includes a cylindrical barrel I0 in which is arranged an elastic tubular filler sack I I constituting an ink reservoir. The filler sack is cemented or otherwise aflixed at its outer end to a bell shaped member I2 having a shank I3 threadedly engaging an interiorly threadedv stud I4 so as to clamp the outer end of the sack between the same and the bell shaped member I2 to thereby close the outer end of the sack. The stud Ill protrudes through a bushing I5 threadedly secured to the outer end of the barrel I0 and a head I6 swivelly mounted on the outer end of the bushing l5 is secured by a screw I1 to the protruding end of the stud I4 for effecting twisting of the sack. The bushing I5 is formed with an annular recess I8 in which the inner ends of studs I9 secured in openings in the cap I8 are slidable to permit of swivel turning movement of the head I6 on the bushing I5.

The forward end of the sack is cemented or otherwise secured about the outer periphery of a tubular member 22 which is threadedly secured at its forward end in an interiorly and exteriorly threaded bushing 23. The said bushing is threadedly secured in the forward end of the barrel Il) with the reduced forward end 24 of said bushing protruding therefrom. A forwardly tapering feed tube 25 is threadedly engaged in the protruding end 24 of said bushing and the same is provided with a longitudinally extending feed duct 23 formed as a continuation of the opening 21 in the tubular member 22. A tapered shank 28 having an interiorly threaded inner end is secured on the projecting reduced end of said bushing with the feed tube projecting forwardly therethrough. The feed tube is provided with an annular flange 3|! which is arranged in an internal annular recess 3l formed in the shank forwardly of the protruding end of the bushing 23 for limiting the axial movement of said feed tube. When the feed tube is in normal forward position the flange 3&1 thereof is disposed in abutting engagement against the annular shoulder 32 formed by the reduced internal diameter of the forward end 33 of the shank 28, and when the tube is movedv inwardly by turning thereof on the threaded engagement with the protruding end of said bushing, the flange abuts against the end edge 34 of said bushing.

An annular cushion element 36 is located between the inner end of the feed tube 25 and the shoulder 31 of the bushing 23 which shoulder is formed by the inwardly directed flange 38. The cushion element 36 is formed of compressible resilient material such as rubber composition which will compress and expand with the inward and outward movement of the feed tube. Arranged centrally within the feed duct 2-6 of the feed tube 25 and extending longitudinally thereof is a tapered stem 39 which is formed integrally with the tubular member 22 and is provided with a reduced terminal 4I! vprotruding through the disengagement with the projecting end 24 of the bushing 23. This will effect movementof the feed tube longitudinally of the 'stem 39 until' the annular flange 30 is disposed. in abutting engagement with the end edge 3 4 of the bushing 23. The inward movement of the feed tube will cause the reduced end 40 of the stem to7 project a greater distance through the orifice 4I so as to break up and dislodge any encrusted ink which may solidify in the discharge orice. The relative movement of the feed tube with reference to the stem 39 will also break up and dislodge any ink which has solidified the duct 26 so that the ink will now freelythrough the discharge orifice.` The ink may be forced through the duct 26by turningV of the head I6 so as to twist the llersack |I as shown in Fig. 5 of the drawings. The pressure thus created in the duct 26 will forcethe dislodged dried or encrusted ink through the discharge orifice 4I.l

'I he ruling blades 43 and .44 are integrallyfconnectecl to abase portion 45 which vis of arcuate formation subtendingV approximately 260"v as shown iii Fig. 6 of the drawings. The base 45 is formed with downwardly directed terminals 4 6 at each side whiohare providedwith inwardly directed lugs 41 engaging in sockets 48 in the outer face of the feed tube 25 to permit of swinging movement of the blades from aligned relation with the pen to an angular relation therewith as shown in Fig.v 2 of theolrawings for cleaning the inner faces of the blades. vThe blades 43 and 4 4 are normally disposed in spaced relation by the spring tension thereof and the blade 43 is provided Awith a screw stud 49 which protrudes through an opening in the blade 44 and is engaged by a nut 50 formovingthe blades inwardly into the proper spaced relation for ruling the desired Widthof line. r'Ihebase portion 45 c lampingly engages the tapered portion ofthe feed tube 25 whe n operative position thereon but the same is suciently resilient to permit of expansion thereof for movement out of aligned relanon. .with `the feed tube- ...The bar 42. itafied to theshank of the stud v49 to dispose the same in position betweenthe blades so as to receive dischargedthrough the orice 4| for vconducting the same to theouter end of the blades. An opening 52 is provided in the wall ofthefe'ed tube 25 which opens into the feed duct 26 adjacent the forward en d thereof and which is riormally closed by a closure member 53 pivoted to the feed tube as at 54.

In order to ll the sack II with ink, the 4head I6 is rotated to twist and tension the sack sd as to expel air therefrom, as illustrated in Fig. 5 of the drawings. When the head I6 is released, the tension in the sack II will cause the same to unwind and produce a suction in the passageway 26 so as to draw ink upwardly therein through the orifice 4| For this purpose the blades 43 and 44 are swung to one side, as illustrated in Fig. 2, andi there'duc'ed end of the feed tube immersed in ink.

The ink may be forcibly fed through the feed duct 26 by turning the head I6 to twist the sack I I. In order to provide for a gravity flow of the ink the closure 53 may be opened to allow air to enter the feed duct 26 which will rise upwardly into the sack I I. Whenever required the feed tube 25l may be moved inwardly on its threaded engagement with the bushing 23 so as to project the reduced end 40 of the stem 39 farther through the orifice 4I to thereby break up and dislodge any encrusted ink in the duct 26 ofthe feed tube.

What is claimed is:
